Web Archiving at UNT and End of Term Harvest 2008

This presentation illustrates the collaborative project with the University of North Texas (UNT) and the United States Government Printing Office as part of the Federal Depository Library Program. The CyberCemetery was created as an online archive of government websites that have ceased operation. This also discusses the UNT collaboration with the United States Government Printing Office, the Library of Congress, the Internet Archive, and the California Digital Library in an End of Term Harvest project in 2008 to archive the Presidential campaign websites before they ceased to exist.

The Second Generation Hypernuclear Spectroscopy at JLab Hall C (E01-011 experiment)

The second generation Λ hypernuclear spectroscopy by (e,e’K{sup +}) reaction has been carried out successfully at JLab in 2005. New configurations, HKS and Tilt method, significantly improved both energy resolution and statistics. Systematic error depend on tuning procedure was estimated by the blind analysis. Analysis is in the final stage. Third generation experiment (JLab E05-115) will be performed in the summer of 2009 w/ new e’ spectrometer (HES).
